Abstract

Dissolved elements of rain water, throughfall and stemflow in Japanese cedar (Cryptomeria japonica) and stands of four deciduous trees, Chinaberry (Melia azedarach), Tulip tree (Liriodendron tulipifera), Wild cherry tree (Purnus jamasakura) and Japanese zelkova (Zelkova serrat) stands were analyzed for 1 year. Analyzed elements were Cl^-, NO_3^-", SO_4^2-, NH_4^+, K^+, Ca^<2+>, Mg^<2+>, Na^+ and pH. The amount of dry deposition and canopy leaching were estimated by the material balance approach. Anoins and cations in dry deposition were almost in equilibrium in the five spices. This equilibrium between anions and cations was mostly maintained in dry deposition. The annual amounts of dry deposition in Japanese cedar were two to four times higher than in the deciduous trees. On the other hand, the annual amounts of canopy leaching in the four deciduous trees were much higher than in Japanese cedar, especially in the case of Tulip tree, where more than 80% of Mg^<2+>, Ca^<2+> was supplied the forest soil by can py leaching. In Japanese zelkova, throughfall and stemflow contained enriched Cl^-, which is believed to have derived from canopy leaching. It was found that some elements supplied to forest soil, especially cations were enriched by canopy leaching in deciduous stands.
